"Thor: The Dark World" has been busy shooting a massive action sequence on its Bourne Woods set recently, with Chris Hemsworth and Jamie Alexander both appearing in numerous set photos with hammer and sword in hand. In the video below, you can actually see the action for yourself, with what looks to be lightning flashing across the battlefield, and clusters of dirt flying up in response. Even with just the thinnest notion of what "Dark World" will actually be about, at least we know we're not going to be wanting for epic battle.
